Fish with its head down and its tail up may not die, but it needs timely treatment. This condition is called swim bladder disease. Although it is a disease, there are many causes, so it is very troublesome to treat. There are many reasons for swim bladder loss, which may be the deterioration of water quality caused by long-term failure to change water, which affects the health of fish, the low oxygen content in water, which is caused by lack of oxygen, or too much feeding.

1. Change water properly: If swim bladder loss is caused by water quality deterioration, the best treatment is to change water. The water quality can be improved by changing water, the ammonia nitrogen content in the water decreases, and the fish recover slowly. Change water too frequently, otherwise the fluctuation of water quality will stimulate fish and even produce stress reaction.

2. Timely oxygenation: Oxygenation is needed for fish farming, especially for larger fish. If oxygen is insufficient, it will also cause fish to lose their swim bladder. In view of this situation, oxygen pump can be used to supplement oxygen. Usually, the air pump should be turned on 24 hours, so as to prevent hypoxia.

3. Reduce feeding: The best treatment for swim bladder loss caused by too much feeding is to reduce feeding. In the daily feeding process, you can feed it two or three times a day. After each feeding, you should ensure that the fish can be eaten within 3-5 minutes, so that there is no risk of eating and losing the swim bladder.
